        Description

        Isotemp Water Heaters General Features:

        • All Isotemp water heaters use two thermostats: a temperature thermostat and a safety thermostat designed to trip in the event the tank is run dry
        • All Isotemp water heaters come standard with a mixing valve
        • Every Isotemp tank features a safety mixing valve that regulates the temperature of the water coming out of the tank so that water heated to 160+ degrees will not scald boat owners or their guests
        • Temperature of the hot water coming out of the tank can be adjusted to the preference of the owner by turning the mixing valve on the water heater
        • This feature allows the thermostat to be set at a higher temperature, while keeping the user safe from scalding
        • It also extends the capacity of onboard hot water by using only a fraction of the water in the tank to produce the desired water temperature
        • Standard heating elements are 750W which won't overload generators or trip dock breakers
